Title: Synchronised copy and original drive for photocopier - with unequal paths and with synchronising sensors and retard control on rollers in each path
Inventor: WASHIO TAKAJI
IPC: G03G15/28
Filed: 1973-07-13
Abstract: A compact photocopier is obtained by having the path lengths of the original and the copy as short as possible for each case, and not equal.

Title: Pneumatic tyre with different hardness rubber - having harder base layer ribbed to line up with tread cuts for increased bonding
Inventor: ROEMER HANS DIPL ING
IPC: B60C9/18
Filed: 1973-12-17
Abstract: The tyre tread is made up of two layers of rubber, an upper, softer layer and a lower, harder layer for a support. The tread pattern is cut into the softer layer. In order to improve the bonding between the layers, and prevent the top layer from stripping off the tyre, the bottom layer is ribbed with a sinusoidal pattern to coincide with the cuts. The tops of the sinusoidal ridges protrude up into the bases of the blocks formed by the cuts while the softer layer dips down into the cuts to form thin bridges between the blocks for extra security.

Title: Container lid sealing strip - has material applied to glued surface of overlapping end to form opening lug
Inventor: FREITAG HAROLD
IPC: B65B7/28
Filed: 1974-05-08
Abstract: The seal is for use with lidded containerS, comprising a flexible strip, glued on one side, laid along the seam between container and lid, with an unglued lug where the ends overlap by which it is pulled off. The lug (26a) is formed by a strip of material placed on the sealing strip (12), being held in place by the glue on the overlapping end, so as to cover this end partly or completely. The material can also be glued on the side where it bears against the sealing strip, but can be of different material and structure to it, e.g. of lesser quality. The sealing strip can be parted off from a storage roll and applied in place as the container is rotated, the covering material being applied at the same time.
Patent DE-2422997-A1 (DE)
Title: Hydrostatic transmission for heavy vehicle - with part of the torque transmitted mechanically via swash plate pump body
Inventor: KIENER KARL DIPL ING
IPC: F16H47/02
Filed: 1974-05-13
Abstract: The engine of the heavy vehicle drives the transmission input shaft which is coupled directly to the swash plate control of the hydraulic pump. The pump body is cylindrical and rotates in special bearings. The pump body is coupled to the output shaft of the transmission so that part of the torque is transmitted mechanically. The rest of the torque is passed through the pump and to a servo motor which is coupled to the output shaft via a reduction gearing. The system enables large torques to be transmitted without requiring large hydraulic pressures, with their inherent sealing gasket problems. The transmission ratio is still controlled by the swash plate setting.

Title: Shoe uppers cutting machine with rotating cutters - is adjusted to sole size and removes cut material ends
IPC: A43D8/34
Filed: 1974-08-19
Abstract: The cutting machine is used for cutting the shoe leather simultaneously by two cutters to form angular cuts.

Title: Workpiece aligning procedure for rods - theoretical deflection is obtained to produce measuring curve to achieve adjustment value
Inventor: EITEL HANS-GEORG
IPC: B21D3/00
Filed: 1974-11-05
Abstract: Workpiece aligning procedure, especially for rods, where at several given measuring points the radial deflection is tested and is adjusted at given selected measuring points. Specifically, of every three measuring points the deflection is identified at both outer points. From this a theoretical deflection at the intermediate measuring point, which simultaneously is the instantaneous adjusting point, is so obtained that this lies on a measuring valve line which connects the two deflection valves at the three outer measuring points. At this adjustment point, there is adjustment with a valve equal to the difference between the deflection at this point and the theoretically evaluated deflection.

Title: Self propelled pneumatic ground boring tool - has separate boring nose actuated by reciprocating impact piston
Inventor: JENNE GUSTAV DR ING
IPC: E21B4/14
Filed: 1975-05-31
Abstract: The selfpropelled pneumatic ramming and boring tool is used especially for making boreholes in the ground. The tool cylindrical housing has a reciprocating nose whose movements are limited by shoulders which contact the stop block ends. This nose is actuated by a reciprocating impact piston within the cylinder housing. This piston exerts an impact on the nose rear face on piston forward travel and the piston deals impacts on its chamber rear wall on reverse travelling of the tool. The opposite end impacts are compensated by an air cushion. The boring nose (3) slides within a bore in the housing fixed nose block (2). The boring nose travel in this bore is only slightly longer than the soil boring step per impact pulse.
